Ambry Genetics

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.247G>A (p.E83K) alteration is located in exon 3 (coding exon 3) of the UFC1 gene. This alteration results from a G to A substitution at nucleotide position 247, causing the glutamic acid (E) at amino acid position 83 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
